The League of Legends World Championship is the annual professional League of Legends world championship tournament hosted by Riot Games and is the culmination of each season. Teams compete for the champion title, the 70 pounds (32 kg) Summoner's Cup, and a US$1 million championship prize.[1] In 2017, the finals were watched by 60 million people, breaking 2016's finals' viewer record.[2] The tournament has been widely praised for its ceremonial performances,[3][4] while receiving attention worldwide due to its multiple dramatic and emotional series.[5][6][7] A donation of US$2 million was raised through the sales of the Worlds 2017 Championship Ashe skin.[8]

LA 2024, which is overseeing the Los Angeles bid for the 2024 Summer Olympics was inspired by the growing success of League of Legends World Championship and is considering to plan and include esports in the Olympic Games if they win the bid. Casey Wasserman, the chairman of LA 2024, suggested using technology used in certain segments of League of Legends Worlds such as augmented reality and virtual reality to make the Olympics more accessible to a younger demographic.

The League of Legends World Championships has gained tremendous success and popularity, making it among the world's most prestigious and watched tournaments, as well as the most watched video game in the world. Due to its success, esports scenes became prominent and widely seen as a potential Olympics event, already being included as a medal event in 2022 Asian Games.[9][10][11][12][13][14]

The tournament is known to rotate its venues across different major countries and regions each year in a rotating manner, particularly in East Asia, Europe, North America, and Southeast Asia. South Korea's SK Telecom T1 currently holds the highest record of wins, with three world championship wins (2013, 2015, and 2016).[15]

Riot Games, which owns League of Legends, commissioned the winner's trophy known as the Summoner’s Cup. Riot specified that it should weigh 70 pounds, though the actual weight of the finished cup was reduced so it would not be too heavy to lift in victory. MacTavish, having already created the Season Two World Championship Cup in 2012, crafted the winners' trophy for the 2014 games.[16]

^Moscow 5 from Russia qualified 2012 Worlds via Europe regional finals. Now CIS/Russia is separated of Europe (EU LCS) and become an independent region that has own league (LCL). So Moscow 5's achievement in 2012 will be counted for CIS/Russia region.

The Season 1 Championship[17] in June 2011, held at Dreamhack Summer 2011 in Sweden, featured a US$100,000 tournament prize pool.[18] 8 teams from North America, Southeast Asia and Europe participated in the championship.[19] Over 1.6 million viewers watched the streaming broadcast of the event, with a peak of over 210,000 simultaneous viewers in the final matches.[20]

After Season 1, Riot announced that US$5,000,000 would be paid out over Season 2.

The final $1 million went to other organizers who applied to Riot to host independent League of Legends tournaments.[22]

The Season 2 World Championship was held in early October 2012 in Los Angeles, California to conclude the US$5 million season. Twelve qualifying teams from around the world participated in the championship, which boasted the largest prize pool in the history of e-sports tournaments at the time at US$2 million, with US$1 million going to the champions.

This change makes the head coach an officially recognized member of the team.[44]

The 2015 World Championship concluded the 2015 season, and was held at several venues across Europe in October 2015. Like the 2014 World Championship, the 2015 World Championship was a multi-city, multi-country event.[45]
